The Double Expanding Truss Rod

Adjustments

The adjustment nut on Modern necks is found at the heel. A convenient side adjust mechanism makes fine adjustments possible without removal of the neck*.

Stability

The Modern neck uses a double-expanding truss rod, installed in a flat slot directly under the fretboard. This rod floats freely within the neck, with only the backward force that counteracts the pull of the guitar strings being transferred to the wood. All the rod's inward compression is absorbed by rod itself. This makes the neck extremely stable through all climates and seasons (perfect for touring guitarists). It also means Modern necks are much less susceptible to warping over time than single rod necks.

Notes

You can choose Modern construction on all Warmoth straight-headstock neck styles. Most Warmoth specialty necks are built using Modern construction only, including the 7/8 Warhead neck, 12-String, Mustang/Jaguar, 7-String*, Bass6*, Gibson® Scale Conversion, and Baritone Scale Conversion* necks.

Many custom options, inluding binding, scallops, or inlay, are only available on Modern construction necks.

The force exerted by the headstock end of the double rod is considerable. There must be a minimum 1/8" of wood below the rod end to prevent wood failure in this area. Thinning a neck beyond factory engineered dimensions is not recommended or covered under warranty.

*Side adjust mechanism not available on left-handed, Baritone Conversion, Bass6, or 7-string necks.
